I hope that helps: ch: it sounds similar to the first syllable of the korean word 화난 without the a in the end, such as in words like Buch, Bach, Dach. Be aware that the 'ch' at the beginning of a word is in Austrian German often pronounced like a 'k', in German German like a 'sch', e.g. China, Chemie. https://www.andrew.cmu.edu/user/ujf/blog/German_ch.html l & r: when pronouncing the 'l', you press the spread out tongue against the upper front teeth close tot he lower front teeth.. For the r-sound press the vaulted tongue's tip at the backside of the bottom of your mouth.
