Even in English ‘this’ changes to ‘these’ before a plural noun and ‘that’ to  ‘those’, which gives you some taste for what German is doing here, e.g. 
dieses Haus (this house)  diese Häuser (these houses).
Jener (that/those) is a word seldom encountered in speech or even . 

in natural writing. There are two more usual ways of expressing ‘that/ those’ in German. The first way is by using der/die/das but with emphasis,  e.g. 
Den Namen kenne ich nicht. (commonly starting with the emphasized word)
I don’t know that name.
Wir wohnen in d e m Haus. (spacing can indicate stress in written German)
We live in that house.

The second way of expressing ‘that/those’ is simply by using dieser and  dispensing with the distinction we make in English between ‘this’ and ‘that’:
Diesen Namen kenne ich nicht.
Wir wohnen in diesem Haus.

There are two other determiners which take the endings of der/die/das but these are most frequently encountered in the plural, i.e. mancher (some, many a), solcher (such), e.g.
Manche Leute mögen es so.
Some people ( many a person) like it like that.
Solche Leute kann ich nicht ausstehen.
I can’t stand such people/people like that.

The most frequent way of expressing ‘such a’ is solch ein, where solch is 
invariable and ein is declined .
