TFTP timeout problem during PXE boot
It looks like the tcpdump output contains only requests and not any responses at all. If this is what is actually happening, then a timeout error is to be expected.

Can we use ftp in place of tftp in pxe boot
In theory, yes you can... you'll just need to design a PXE standard extension for FTP, then write a new netboot firmware to implement that extension, then flash it to your NICs.
