It's difficult to tell just from the one Hfl, you really need to follow up both forwards and backwards on all of these people.
But my educated guess is as follows:
Sven Nilsson, born 02 Jan 1821, was widowed 22 Aug 1860 (at a guess, his wife died in childbirth - two years between children), moved to this farm in 1869 bringing his two daughters, Botilla (b. 27 Dec 1856) and Johanna (b. 31 Dec 1858).
At the same time - 1869 - the female farmhand Martina Lindqvist (born 05 Feb 1841) is hired. Martina and Sven are soon an item and are forced to marry 16 Nov 1870 - their first child, Nils Peter, is born already 18 Jan 1871 (i.e. three months after the wedding). The couple then have another child, daughter Anna Sofia, 21 Apr 1874. Then, catastrophy: Sven dies 27 Jul 1875 - and Martina is already pregnant with their third child, daughter Hilda Maria, born posthumously 11 Jan 1876.
Martina certainly doesn't marry in this Hfl; she couldn't marry for a year after her first husband's death.
The column Äktenskap means Marriage; first subcolumn is Gift, Married, the second is Enkling eller Enka, Widower or widow.
Column Flyttat is Migrated - and this column is migrated from, migrated to is on the opposite page, to the very right.
Column Död is Dead.
Enumeration in the Hfl is always in reference to the head of household, which is why the daughters are just given as daughter, it doesn't matter that the mother is their step-mother - if it had been the wife's daughters in a previous marriage they would have been given as wife's daughter (or should have been, some clerics were lazy).
It can safely be assumed that both Sven and his daughters as well as Martina moved in at the same time. The date for moving was 24 Oct - all other dates are very unusual, though they sometimes happen of course. You took up a new tenancy or began a new employment on 01 Nov. The week in between was slankveckan, lean week, when everybody had a vacation but at the same time didn't get paid and were usually not fed either.
Martina started out as a female farmhand and was later promoted to wife, because she appears twice on the page, with dates fitting all events. When she is moved up to wife, the Migrating column says from below (Nedans.).
Anders Johansson isn't really connected with the Sven-and-Martina family. He's just a man they share their farm, and perhaps their house, with. He moved in in 1863 and moves out in 1873.
