Bandwidth sharing

Hello
I have a problem with my configs.
Indeed I have a mikrotik RB1100AHx2 router which is remote and which manages the connection of two different clients.
the concern is that I wanted to separate the bandwidth of each client.
Example I send 5Mbps or client one must receive 3Mbps and client 2 must receive 2Mbps.
on my attached file you will remap the ports dedicated to each client.
Thank you in advance.
