We don't know much about what PAF has on its list or will have on it in few years. But the following is kind of a public:
1. F-16C/D
2. F-16 A/B (MLUed)
3. JF-17
4. J-10
5. FC-20 (still a UFO)
JF-17 is going to replace Mirage-III & V & F-7 series. CAC is also in R&D to develop ground attack version of JF-17 which will replace the aging A-5/Q-5 Fantans.
FC-20 is something I have been trying to figure out for a long - at least since I came to hear about it. In the beginning several of us, including yours truly, did find an information about a Twin-engine (probably with TVC), super cursing ability, semi stealth, powerful radar, greater range etc J-10 but thats all that was there. We haven't seen any other credible information. I don't even know if thats the FC-20 or Super J-10 or what ever they are calling it now.
AFAIK FC-20 could be J-11B.
On the AWACS side:
1. ERIEYE
2. E2C Hawkeye (but operated by PN on its P3C Orion aircrafts)
3. Chinese Y-8/KJ-200 AWACS (MoU was signed with possible ToT, however we still don't know if the AWACS agreed upoin is KJ-200. But since it is rumored to be the one laid down for PAF in 1996 thats why we are pointing to it)
* IL-78 are also being purchased as air-2-air refuel tankers. (made public by ACM)
About the stealth program. China is going with 2 J-XX programs (J-13 & J-14) & FC-20 is just a stop gap. There is a possibility of Pakistan Aeronautical Complex (PAC) pitching in with the CAC's project (I don't know if CAC is working on J-13 or J-14). Even if Pakistan does not capture the joint venture I am sure J-XX is the stealth aircraft PAF will have - most probably from CAC.
Not to forget that PAC engineers are educated from western countries & have worked on several western aircrafts & their avionics. Plus the experience from manufacturing/assembling western avionics within Pakistan when ToT is received. These engineers can be handy.
As for other western aircrafts, I guess one has to wait & see how J-XX program goes.
