The lesson that drew me here said the correct answer was in the imparfait.  Ils ne habitaient plus ici but the examples in the lesson do not transition from the present to the imparfait. What makes the difference?

in this sentence from  a roman policier La salle des meurtres by Phyllis Dorothy James 

L’appartement, qui donnait sur Kensington High Street, arborait l’ordre excessif et impersonnel d’un logement préparé pour la visite de nouveaux locataires. L’atmosphère était un peu confinée ; bien qu’occupant un étage élevé, Dupayne avait pris la précaution de fermer ou de verrouiller toutes les fenêtres avant de partir en week-end. 

Here  bien que was not followed by subjonctif ! is that correct ? and would you replace it by bien qu'occupant un étage élevé, Dupayne ait pris la précaution .....

I gave elle s’assoit avec son fils but this was corrected to elle s’assois which isn’t the 3rd person .

Could you please clarify if these go before or after a noun - 

1. Fou/Fol/Folle (crazy)

2. Mou/Mol/Molle (soft)

3. Mince (slim/thin - opposite of gros/grosse)

4. Court/Courte (short - opposite of long/longue)

5. Mignon/Mignonne (cute)

6. Bas/Basse (low - opposite of haut/haute) 

I find that in many of the lessons, the synonyms are often not taken as an alternative. For example "des fois" was not taken as correct for "sometimes". Another example, "cueillir" was marked wrong for "picking", and an alternative "ramasser" was suggested as a correct answer. I'd suggest to expand the choices of synonyms.
