For the time attack medals, you do its quest

First do "Strange Battle" in the Kid Buu event

With the above team, if you skip all the pickups, you will most likely be able to clear it in a minute thirty secs, which gives you a total of 2 medals

Then do the same for 'Limit breaking saiyan' in Surpassing all

You should be able to clear the first stage within a minute, so another 2 more medals

Inimitable fusion first stage clear it in a minute fourty five you will get another two medals

Terrifying transforming majin first stage complete it in minute 30 and thats another two medals

That will give you a total of 8 medals, good enough to Dokkan Boujack. For his other medals, you do the Hero Extermination Plan event to get them. Just spend one weekend grinding it and you get yourself your very first LR at level 120ish
