I searched Egyptian T-80 and found nothing reliable, only strategy page and wikipedia are reporting that Egypt has T-80's but Strategypage and Wikipedia aren't considered reliable by any military enthusiast/expert:

I found Nothing regarding Egyptian Tunguska:

Regarding Egyptian MIG-29, most of the sources are only saying that Russia offered Egypt MIG-29's and some SAM's, they are not stating that Egypt has acquired MIG-29's or SAM's:
Atom in Exchange for Weapons - Kommersant Moscow
"Moscow is expected to
offer to Cairo (meaning the deal is not official) during today’s negotiations to supply Russia-made air defense systems, fighter jets, and training aircrafts. However, the chances for a more or less considerable expanse are small.
“Russia’s opportunity to export weapons to Egypt is extremely limited due to that country’s dependence on U.S. aid,” said Konstantin Makienko, expert of the Strategy and Technology Analysis Center. Indeed, Washington announced in July 2007 that it prolongs for another decade the program of financial aid for Egypt. Between 2008 and 2017, the U.S. will allocate some $13 billion to Cairo for purchasing the weapons. No wonder that Egypt’s armed forces are oriented chiefly at U.S. military equipment. The country’s air force includes over 200 F-16 fighter jets and several tens of AH-64D Apache Longbow strike helicopters. In the early 2000s, Egypt’s army acquired a large set of M1A1 Abrams tanks. In 2006, the U.S. began supplying PAC-3Patriot air defense systems to Egypt.
Meanwhile, the Russia-Egypt military-technical cooperation, which was of great extent in the 1960s, was minimized in 1972. Afterwards, the military equipment supplies were very small and rare. So, in 1999-2000, Cairo received 20 Mi-17-1V and several Mi-172 helicopters. Back then, Russia and Egypt also signed a $150-million contract on modernizing 50 S-125 ‘Pechora’ air defense systems, supplied to Egypt back in the Soviet times. In 2005, they signed a small contract on supplying four ‘Tor-M1’ complexes to Egypt. Same year, they signed an agreement on modernizing old Soviet-built ‘Kvadrat’ anti-aircraft missile complexes. Apparently, the contract’s first stage was a trade-in, that is the direct supply of a small party of ‘Buk-M1-2’ complexes to replace old ‘Kvadrat’s. In mid-2007, Russia and Egypt signed a contract on supplying ZSU-23-4-M4 ‘Shilka-Strelets’ anti-aircraft self-propelled mounts.
In April 2006, MiG Corporation’s deputy director general and deputy chief designer Sergei Tsivilev made a sensational statement about the plans to supply MiG-29 fighter jets to Egypt. Later it turned out that Moscow had offered to Cairo to buy 40 MiG-29SE fighter jets or more modern MiG-29SMT. The deal was planned as a trade-in as well. The new jets were to be supplied instead of over a hundred of old MiG-21, which remained without Russian technical maintenance for over 30 years. The contract was estimated at $1.5 billion. However, that so large acquisition of jets must have proven impossible due to U.S. pressure. Along with MiGs, Moscow offered to Cairo its Yak-130 and ‘MiG-AT’ training aircrafts, which were to replace outdated Czech-Slovakian L-39 jets. However, these plans as well are far from implementation. Anyway, despite pessimistic prognoses from experts, Moscow truly hopes that it can manage to bring Russian weapons back to Egypt’s market in package with the nuclear deal"
besides that only Iranian Forums are discussing MIG-29's, T-80's, and SAM systems and these cannot be considered reliable sources.
