Okk..lets discuss about the part..
JF-17 easily counters MIG-29s and Mirages(Old?? I think you meant Mirage 2000 and not upgraded ones like Mirage 2000-5 and Mirage 2000-5-9)..ald FYI,IAF MIG-29s are of SMT standard.

now,lets compare...
JF-17 vs Mig-29(SM version)
Load- 3400 kg with Weapons vs 4000 kg weapons in Mig-29S
Engine- 1 vs 2,which pushes it upto Mach 2.25,where JF-17 can only reach at Mach 1.6.So,Mig-29 can outruns JF-17.
same TtoW
Radar- 105 km (65 mi) in look-up mode and ≥ 85 km (53 mi) in look-down mode(KLJ-7) vs 120 km for fighter sized target(10 tracked,4 attacked) (Zhuk-ME)
Hardpoint- 8(3400 kg) vs 7(4000 kg)
BVR-PL-12(70 km) vs R-27(latest ones having range over 130 km),R-77(greater than 110 km)
WVR capability is about same- Python,Sidewinder vs R-73(R-73 possibly has little advantage because of its greater HOBS and range)
So,no.JF-17s can't "Easily" handle MIG-29 SM as MIG-29 has better RADAR,better Missiles and It is one of the greatest dogfighter ever designed..remember,I choose MIG-29 SM which is having little bit A2G capability and not MIG-29S which was an "in between product" in my opinion.It came to existence 20 years before JF-17 came.I didn't compare it with MIG-29 SMT which IAF has..I didn't enter into unknown domains like IRST,Jammer etc.I don't know if JF-17 uses Jammer.MIG-29 uses L203 Gardenia..
it is a good jammer..

Now..
JF-17 VS MIRAGE-2000(Base Version)
Engine-1
Speed- Mach 2.2
TtoW-.7,lesser than JF-17
Hardpoint-9,can carry some 6300 kg..far greater..
Radar-Thomson-CSF has range over 100 km(same),RDY has around 110 km range.
Armament- MICA- 50 km,Super-530(40 km)..IAF uses R-27
Magic-17 km
uses Dassault Sabre
radar jamming and deception pod.
So,nope..spec is around same,but due to better sensors,Mirage has advantage.India uses much upgraded version of this basic version and now they're upgrading them again.
