Danny Collins, Danny Pugh and Andrew Davies are all wanted by Pompey, says The Sentinel.
"These are lads who have not been playing enough recently," Pulis told The Sentinel, "and so we want to get them out and playing football until Christmas. It's important for Danny Collins to be playing at his age and because he's in the Welsh squad.
"Danny Pugh has been knocking on my door to go out and I've relented because he's such a great lad.
"It's the same for Tom and Tongy. I'm surprised no-one has come in for Tongy because he's had a good pre-season and looked as sharp as at any time with us."
