can someone add these plugins please

They don't add it to your server, they add the mods to Aternos, then you need to go to the bukkit tab under plugins at the bottom of the page and click files and plugins, then search the plugins and add them

On the Aternos website they cannot add plugins specifically to your server, what they do is, someone requests a plugin or multiple plugins, from there they see if it will work with their servers, if it does, great! It will be added to Aternos, and if you look at the top of the page where it shows Files and plugins, that is where the plugins are added, to play using plugins you need to scroll down to the bottom of the Aternos page and click the tab that says Plugins with a down arrow next to it, click bukkit, then choose the bukkit version that works with your plugins (aka 1.8 since your plugins all have that version) then scroll all the way up again and click files and plugins, then select install plugins and search the plugins you want for your server, then click my server and hit start! Just be sure to wait on the plugins to be added first so you know what is there and what isn't.
