In eMule can I see if I get friendslots from someone?

Can you see if I add you as my friend?

If I give a friendslot to someone can I give it to someone else when I see the first friend starts downloading or will that remove the first friend from dl?

First 2 no. Friendslots are just a way for you to give someone the first position in your upload queue, and is totally to do with 'you end' of emule.

Multiple friends slots is not supported by most mods at the request of the emule developers (to prevent winmx style trading)... which is probably for the best. The best way to get files out is to appropriately manage your upload priorities rather than utilise lots of friends slots. If your client doesn't support multiple friends slots, then the original person will lose his queue position and you'll have infact reset his queue position, and he'll have to start all over again.

Some mods do support multiple friends slots, morphXT does. However to combat the trading it doesn't include the slots in your upload/download ratio and has an inbuilt hard limit of 1:3, when you hit this (ie. downloaded 3 times as much), it will put a little R icon next to your downloads meaning they are restricted. These are measures to combat trading and should be very welcomed.

Ok, sound better to manage my upload priorities instead, i will do that. What films should I have for the highest priorities ( except looking in the forum here what members want ).
I want to collect points from the right users who have most and best zombie film so I guess I put the highest on the zombies I have.

Well anything with shareconnector, sharethefiles or any other retagging site in the filename should be put on very low priority for a start.

Then, you need to use the "complete sources" column to gage how well spread something is, and then give the ones with lower numbers higher priorities.
