good evening!

i plan to allocate internet speed at home to 4 users like the one below:
User 1 = 10mbps
User 2 = 5 mbps
User 3 = 5 mbps
User 4 = 5 mbps

(1) Is this possible?
(2) Can this be done using the telco modem/router (globe/pldt)
(3) do i need to purchase an entry level third party wifi router? (what features do i need to look for?)
(4) how to do it?

thanks
