What are the ultimate objectives in Hinduism?
Is Moksha the only ultimate objective?

A:

No, moksha is not the ultimate objective for all Hindus. Moksha is the goal for Advaita Vedanta. Vaishnava objective is Vaikutha where a Vaishnava will enjoy bliss with Krishna or Narayana eternally. 
People who follow Purva Mimamsa want to go to heaven at least until the merit due to Yajnas are exhausted. People who follow Samkhya probably want to be Prakritilina which will allow them to be controller of nature at least for one cycle. 
The objective of Yoga is Kaivalya which is a state of permanent cessation of the Gunas which work as cause and effect. 

Kaivalya or liberation (of Purusa) is the state of permanent cessation
  of the Gunas which work as cause and effect and after having brought
  about experience and liberation, have no further service to render to
  Purusa. In other words, Kaivalya is the state which is reached when
  the Supreme Consciousness is established in Its own self, i.e., when
  It is unrelated to or unconcerned with Buddhi, and remains alone for
  all time.

English translation by Swami Hariharananda Aranya of Vyasa's Commentary on Yoga Philsosophy of Patnajali 4.34

A:

The ultimate objective in Hinduism depends upon what school of thought or philosophy you are following. But the common thing in all of them is the same, liberation from this material mode of existence. So getting rid of Samsara is the ultimate objective. But while staying on this material plane for a proper living many other things are required. Hence, taking those into account Hinduism lays out four objectives in life known as chatruvarga or the four purusarthas. They are: 

Dharma (this is the first priority, evey other objective must be done abiding to dharma) 
Artha (earning money for a sustainable living in the right way)
Kama (creating progeny with wife for continuation of the race)
Moksha (renouncing worldly activities and focusing on liberation from this material existence of repeated birth and death)

While these are the common objectives for a human here as per Hinudism, different philosophical systems layout their different objectives. For example, in the path of bhkati the first three are called bhukti (enjoymnet) and moksha is called mukti (permanent liberation into the absolute). And a devotee renounces both for eternal  association with God. For them Bhkati is the supreme most dharma:

sa vai puṁsāṁ paro dharmo yato bhaktir adhokṣaje
  ahaituky apratihatā yayātmā suprasīdati [SB - 1.2.6]
Meaning
  The supreme occupation [dharma] for all humanity is that by which men can attain to loving devotional service unto the transcendent Lord. Such devotional service must be unmotivated and uninterrupted to completely satisfy the self.

A:

Moksha is only a purushartha (1 out of 4) - a duty according to the Hindu philosophy.
The main goal is not just attaining Moksha but to serve the Creator of this universe, the Bramha (not lord Bramha). Everyone has his own jeevana karya out of which the primary goal is to be united with the ultimate God (Moksha).
The most important of all goals is to be a Human as vedas say manurbhava
(be human).
Also there are varying definitions for Moksha for every other pantha, but most important is that be a manushya and serve god as manushya.
