How many angels fought with Muslims?

3:124, 126
When thou didst say unto the believers: Is it not sufficient for you that your Lord should support you with three thousand angels sent down (to your help)?
Nay, but if ye persevere, and keep from evil, and (the enemy) attack you suddenly, your Lord will help you with five thousand angels sweeping on.
Allah ordained this only as a message of good cheer for you, and that thereby your hearts might be at rest - Victory cometh only from Allah, the Mighty, the Wise.

8:9-10
When ye sought help of your Lord and He answered you (saying): I will help you with a thousand of the angels, rank on rank. Allah appointed it only as good tidings, and that your hearts thereby might be at rest. Victory cometh only by the help of Allah. Lo! Allah is Mighty, Wise.
It was ranks each one consists of one thousand: rank on rank. So verse 8:9-10 talks about the event in general, where verses 3:124-126 are more specific.
