Uploaded Guns / They Show as Error's

Okay so me and my friend uploaded Glowstick’s, Binachi-6 (or w/e) and crossfire,
we used his computer through teamviewer to upload them to filezilla,
also added Jihad bomb and afew others off of his computer,
and when he joins the server they are all error’s for him but for me and other’s they are perfectly okay besides glowstick’s and jihad bomb.

Are the files in a fast download? Does your friend have CSS mounted? (assuming those are using CSS models)

1: No we uploaded through direct upload with FileZilla
2: Yes, and i dont think they use CS:S Models

and he can see everything perfect in singleplayer but not in the server,
and we uploaded them successfully as others and me can see them
